Definitions
- the invention relates to a device attachment for mounting an aircraft engine on a mast fixed to a structural element of the aircraft, such as a wing or fuselage element.
- the hanging device conforms to the invention can be used on any type of aircraft.
- a preferred application concerns aircraft of recent construction, whose engines are equipped with blowers of very large diameters.
- the engines fitted to aircraft are either suspended from a mast fixed under the wing of the aircraft, either hooked laterally to a fixed mast on the fuselage of the aircraft.
- the connection between the engine and the mast is generally provided by a front hooking device and a rear hanging device. These devices hooking function is to transmit to the aircraft, through the mast, the efforts generated by the engine.
- the engine is assigned a orthonormal reference frame OXYZ, in which the axis OX, directed forward, is oriented along the longitudinal axis of the motor, the OY axis is oriented laterally in a plane horizontal and the OZ axis is oriented vertically towards the top.
- the forces transmitted to the structure of the aircraft by the attachment devices are mainly engine thrust forces, applied substantially along the OX axis, forces lateral due in particular to a gust of wind, applied substantially along the OY axis, and forces due to the engine mass or generated in the event of an aircraft crash, applied substantially along the OZ axis.
- the hanging devices transmit to the structure of the aircraft a moment along the OX axis, due to movement rotary motor.
- the forces applied along the axes OY and OZ are reversed.
- the housing central of the turbojet engine is directly attached to the mast attachment by a front clip and a clip back.
- the front attachment resumes simultaneously the forces along the axes OX, OY and OZ and the rear attachment takes up the efforts along the axes OY and OZ as well as the moment along the OX axis.
- a front attachment is interposed between the mast and the housing of the turbojet engine and a rear attachment is interposed between the mast and the central casing of the turbojet engine, as in the "core” type assembly.
- the front attachment takes up the efforts according to the OY and OZ axes and the rear attachment takes up the forces along the axes OX, OY and OZ as well as the moment along the OX axis.
- resumption of the thrust along the OX axis is effected by means of two connecting rods connecting the rear attachment to the front part of the housing central of the engine.
- the return rods of thrust are sized to take up an effort important, oriented along the longitudinal axis OX of the engine. They are therefore very long rods (about 2 m).
- the hanging device called upon to perform this function should preferably be easily removable to avoid loss time when removing or installing the engine.
- the main object of the invention is a simplified hanging device, capable of being used in a new engine mounting system aircraft on a rigging mast, in order to ensure the transmission of forces according to a single direction, in a reduced location and disturbing aerodynamic air flow as little as possible.
- the invention also relates to a hanging device capable of being easily disassembled, if necessary.
- this result is obtained by means of a hooking device aircraft engine on a mast attached to an element of structure of the aircraft, said device comprising a main hanging structure and a structure emergency attachment, characterized in that the main hanging structure ensures the transmission of forces directed towards the mast, according to a one and only direction, substantially radial by relative to a longitudinal axis of the engine, the structure emergency attachment comprising an element fixed to the mast, which is also part of the hanging structure main.
- the element common to the structure main attachment and to the attachment structure emergency comprises advantageously at least two separate parts, capable of transmitting independently from each other the efforts oriented according to said direction. So if one of the two breaks parts, the transmission of forces continues to be secured through the other room.
- the main attachment structure further includes a substantially articulated lifter in its center on the element common to the structure main attachment and to the attachment structure and two connecting rods hinged to each of the ends of the lifting beam, so as to connect it to an engine housing.
- the lifter is preferably articulated on the element common to the structure main attachment and to the attachment structure emergency by an oriented hinge pin substantially parallel to the longitudinal axis of the engine.
- connecting rods are advantageously articulated on the lifting beam and on the motor housing by swivel pins. This arrangement avoids that parasitic forces, that is to say oriented according to a direction different from the direction of transmission of the aforementioned efforts, do not pass through the hanging device.
- the element common to this structure and to the main attachment structure is advantageously connected to the housing by a link with play, not working when the hanging structure main is operational.
- the link with play includes another axis of articulation, mounted on the element by through a ball joint, and a hole formed in a clevis secured to the casing and traversed with clearance by said other axis of articulation.
- the attachment device according to the invention is advantageously used to connect the mast to the housing fan of this turbojet engine.
- the element common to the structure main attachment and to the attachment structure backup includes a disconnection plan, planned for be fixed to the mast by fixing means.
- a hanging device according to the invention, applied to the case of an engine mounted under the wing of a aircraft.
- an identical hanging device can be used to mount a engine laterally against the fuselage of an aircraft.
- the hanging device shown in the figure is used to connect a motor housing C of which wish to carry out the attachment to a mast (not shown) fixed under the wing of the aircraft. More precisely, in the most frequent case where the engine of the aircraft is a turbojet engine, the attachment device according to the invention is advantageously interposed between the mast and the fan casing C of this turbojet engine.
- the attachment device illustrated on the figure is a particularly simple device and compact, sized and optimized so as not to transmit to the mast that the efforts exerted by the motor in one direction, oriented towards the mast, substantially radially with respect to a longitudinal axis of the engine.
- the attachment device conforms to the invention only ensures transmission to the mast of thrust forces, directed substantially along the axis vertical OZ, in an orthonormal coordinate system OXYZ in which the OX axis is oriented forward along the axis longitudinal of the engine, the OY axis is oriented laterally and located in a horizontal plane and the axis OZ is oriented vertically upwards.
- the hanging device is applied to the mounting of an engine on the fuselage of a aircraft, the only forces transmitted by this device are oriented substantially along the lateral axis OY.
- the device of attachment comprises a structure main attachment, which normally ensures the integral transmission of forces when it is operational, and a hanging structure of rescue, through which a part of the efforts to be transmitted after one of the parts of the main attachment structure.
- the main attachment structure and the emergency hanging structure include a common element, generally designated by the reference 10 in the figure.
- element 10 Given its vital function in the attachment device, element 10 is formed of two separate parts 10a and 10b, through which all the forces transmitted between the engine and the mast, under normal conditions as in emergency conditions. More specifically, each of parts 10a and 10b forming the element 10 is suitable for alone, transfer all of these efforts.
- the two parts 10a and 10b are joined back to back by such that the element 10 thus formed has in section in the XOZ plane the shape of a T.
- the parts 10a and 10b are joined together, for example by means of bolts (not shown).
- the element 10 comprises a yoke vertical male 12, formed half in each of parts 10a and 10b, as well as a horizontal sole 14, equally formed equally in each of the two parts constituting the element 10.
- the flat upper face of the sole 14 of element 10 forms a disconnection plan, provided for be fixed under the hanging mast suspended from the wing, by any suitable fixing means such as barrel nuts, or the like. To facilitate the reading the figure, these fixing means have not been represented.
- Male yoke 12 projects downward at starting from the sole 14, in a plane perpendicular to the longitudinal axis OX of the engine. Near the sole 14, the yoke 12 is crossed by a first hole (not shown), in which an axis is mounted of articulation 16. This axis of articulation 16 is oriented substantially parallel to the longitudinal axis Engine OX. It is an integral part of the structure of the device, including the others constituent elements will now be described.
- the main hanging structure of the hanging device comprises also a lifting beam 18, which is articulated substantially in its center on element 10, by through the hinge pin 16. More specifically, the spreader 18 extends in a direction substantially parallel to the lateral axis OY, of on either side of axis 16 and it is mounted on this axis so as to be able to pivot freely in relation to item 10.
- the spreader 18 is a single piece, which has two parallel branches 18a, 18b located on either side of the male yoke 12. These two branches 18a, 18b are connected to each other, on each side of the male yoke 12, by members 18c, one of which only is visible in the figure. Beyond these frames 18c, branches 18a, 18b of spreader 18 form female yokes in which are received pivot axes 22 oriented parallel to the pivot axis 16.
- the main hanging structure further includes two connecting rods 24, connecting each end of the lifter 18 to motor housing C.
- These connecting rods 24 are located in the median plane of the spreader 18, perpendicular to the longitudinal axis OX of the engine. More specifically, a end of each of the connecting rods 24 is articulated in the female yoke formed by the adjacent end of the spreader 18, via axis 22 and a ball joint (not shown).
- each of the connecting rods 24 is articulated in a female yoke 26 provided for this effect on motor housing C.
- This joint is provided by a pivot pin 28 as well as by a ball joint (not shown) interposed between axis 28 and the end of the corresponding rod 24.
- the attachment structure of relief is mainly constituted by element 10 already described.
- a second hole crosses the male yoke 12, near its end lower.
- a pivot pin 34 is mounted in this second hole via a ball joint (not shown).
- the pivot axis 34 crosses with play a hole 32 formed in a female yoke 36 making integral part of engine casing C.
- pivot axis 34 is oriented substantially parallel to the longitudinal axis Engine OX.
- the clearance formed between hole 32 and the axis of pivot 34 is dimensioned so that the female yoke 36 is never in contact with the pivot axis 34 carried by the male yoke 12, when the structure main attachment is operational.
- the hole 32 can possibly have an oblong shape in the circumferential sense.
- the device When the aircraft is in flight, the device is subjected to thrust forces along the OX axis, to lateral forces along the OY axis and forces due to weight of the motor along the OZ axis.
- Pushing efforts are resumed mainly by one or more other devices hooking (not shown) by which the motor is also connected to the mast. Because the connecting rods 24 are mounted on the lifting beam 18 and on the casing C by spherical axes 22 and 28, if a small part of the thrust forces along the axis OX is not taken up by another attachment device for the mounting system, in no case may it be transmitted by the hanging device according to the invention.
- the yoke 12 becomes active as an attachment structure for relief.
- the yoke 12 automatically performs the hanging function and passing efforts, in association with each other connecting rod 24 still intact and the spreader 18. The efforts are therefore correctly transmitted to the mast.
- the clevis 12 provides the same attachment and passage of efforts than previously, in association with the still integral part of the structure main attachment. The same applies in the event of rupture of one of the axes 22 and 28.
- the hanging device according to the invention is a compact device, minimizing flow disturbance aerodynamic.
- this device is particularly simple, both in its design and in its production. In particular, all parts are visible and can be inspected and dismantled without disassemble the engine.
- the mounting and disassembly relative to the mast is easy, thanks to the means fixing (not shown) interposed between the sole 14 of element 10 and the mast.
- the device is dimensioned and optimized to take back a single type of effort and to provide a backup function in the event of a fault of a room.
- the invention is not limited to embodiment which has just been described as example. So at least some of the male yokes and females connecting the different parts of the device, through the pivot axes, can be reversed without departing from the scope of the invention.
- the element 10 can in particular be formed by the assembly of two U-shaped section pieces, one inside the other.
- the element 10 can possibly be made in one piece, sized to this effect. Furthermore, if the device is advantageously placed between a mast and a housing turbojet fan it can also be used to connect a mast to any other crankcase plane. Finally, as we have already observed, such a device can also be used in the case of a engine attached laterally to the fuselage of an aircraft.
